Seaweed Sargassum sp. which is not used for food or (for sale) is usually waste and it has the potential as rnimal feed stuff especially as mineral source. This study aimed to evaluate the chemical composition of seaweed (Sargassum sp.) based on different drying methods. Seaweed Sargassum sp. was obtained from Seprnjang Beach in Gunungkidul Disfrict, Yogyakmta. The seaweed was cleaned from dirt and other materials before drying process. The drying process for seaweed was divided into two methods. The first method was sun-dried base for three days started from 07:00 Am to 14:00 PM, the second method was oven-dried base at temperature of 550C for four days. All of the seaweed were grinded, then analysed using proximate analysis. Data obtained were examined by t-test. The results indicated that different drying process (sun-dried and oven-dried) did not have significrnt effect on the dry matter (90.07+3.73% vs. 89.72+0.54%), ash (41.77+7.30% vs. 46.56+2.01%), orgrnic matter (58.23+7.30% vs. 53.44+2.01%), crude protein (7.56+1.32% vs. 8.77+0.61%), and crude fat (0.78+0.25% vs. 0.62+0.24%) content.. Thus, the sun-dried method cm be used optimally to preserve seaweed Sargassum sp. without affect the chemical composition.
